FIELD OF THE DISCLOSURE

The present disclosure relates to floors, and particularly, to a wood-bamboo double layer floor.

BACKGROUND OF THE DISCLOSURE

On the present market, there are many kinds of wood-bamboo composite floors. Most wood-bamboo composite floors include a multilayer wood board with wood fiber directions arranged in a crisscross pattern, and a bamboo board adhered between the multilayer wood board or to surfaces of the multilayer wood board, the bamboo board is spliced from bamboo sheets, the wood board and the bamboo board are laminated and adhered to form the composite floor via using adhesive, and then patchwork opens are defined around the composite floor, such as a Chinese patent with the application number 200620059793.5 and entitled with “a wood-bamboo multilayer composite floor”. In the wood-bamboo multilayer composite floor, no matter bamboo board itself or the combination between the multilayer wood board and the bamboo board, all need to use a lot of adhesive. Though the preset floor industry requires using environmental adhesives, the environmental adhesives can also bring some harmful to the environment and human health. And methods for making the wood-bamboo composite floor are complex, the production efficiency is low, flexibility of the composite floor is poor, and the foot feels is also uncomfortable.

According to the present application disclosed the wood-bamboo double layer floor, the whole wood-bamboo double layer floor only includes two pieces of wood boards, it can reduce the usage of adhesive. The top panel is made from top grade wood, which has great strength and hardness, good abrasive resistance, pretty wood grain. The bottom panel is made from wood, which is growing fast, many storage, little utility value, cheap price, such as fast-growing wood, pine. The strength and flexibility of bamboo strips are much greater than those of wood. Bamboo resource is great rich, the use of bamboo is smaller than that of wood, and the cost of bamboo is low. Therefore, it can reduce the cost of the floor, save the usage of wood and develop the using of bamboo resource. The strength and stiffness of the floor through adjusting the usage of bamboo strips, sectional shape, the distribution and arrangement of the bamboo strips in the floor, and fiber directions of wood and bamboo strips, is to satisfy different requirements of strength and flexibility, and also control the deformation of wood. The combination of the two materials of wood and bamboo, looks like rebars applied in concrete, but comparing to the traditional and whole bamboo inserted in the floor, it is more flexibility and feeling of users' feet is more comfortable. In addition, it requires a strict flexibility for room sports ground, such as gymnastics ground, table tennis ground, high jump ground, tennis filed, and so on. The wood-bamboo double layer floor can satisfy the special requirements. The wood-bamboo double layer floor has a simple manufacturing process, high production efficiency, low material usage and production cost, good environmental protection, good use property, which can meet a various of special using requirements of grounds.
